Current market value may vary from region to region but I'll give you the
currently acceptable prices back East:

The keyboard doesn't really change the price. $35 is average for a
working console/PS/Modulator. If you throw in the books that came with
it, the customer might even smile ;)

Now THAT'S a toughie. There is nothing to judge it against since this is
not a normal TI 'for-sale' type item. The Adam keyboard I got sold for
$10 at the local Rat Shack store a couiple of years ago. The standard TI
keyboards sold for $5 at the same place. SWAG would put the price at
about $45 (the convenience of the 6 foot cable is worth $5).

We'll have to break this down. TI interface cards go for about $35 but I
HAVE heard of them going for upwards of $50. 

The SS drive is probably a Shugart SA400L which makes it SS/DD (180k).
Worth about $10-15 on a good day. I've seen them at Hamfests for as
little as $5.

P-Boxes are in demand. With Flex-cable, it's worth about $75. Geneve
owners sometimes offer to kill for P-boxes ;)

>    SS external disk drive.

Assuming this is the TI version of an external disk drive, same price as
above for the drive itself, figure about $35-45 for the power supply/box

$50. No guessing here.

These prices are from experience at MANY hamfests and TI faires. Dealer
prices (when you can find them) are unreasonably high in  most cases.

Hope this helps. I'm also posting this e-mail to the 'net for others who
may be interested,
